Bit Bit
Name
Initial
Value R/W
Description
5 TDFE
1 R/W
*
Transmit FIFO Data Empty
Indicates that data has been transferred from SCFTDR
to SCTSR, the number of data bytes in SCFTDR has
fallen to or below the transmit trigger data number set
by bits TTRG1 and TTRG0 in SCFCR, and new
transmit data can be written to SCFTDR.
0: A number of transmit data bytes exceeding the
transmit trigger set number have been written to
SCFTDR
[Clearing conditions]
•
When transmit data exceeding the transmit trigger
set number is written to SCFTDR after reading
TDFE = 1, and 0 is written to TDFE
•
When transmit data exceeding the transmit trigger
set number is written to SCFTDR by the DMAC
1: The number of transmit data bytes in SCFTDR does
not exceed the transmit trigger set number (Initial
value)
[Setting conditions]
•
Power-on reset or manual reset
•
When the number of SCFTDR transmit data bytes
falls to or below the transmit trigger set number as
the result of a transmit operation
*
Note: As SCFTDR is a 64-byte FIFO register, the
maximum number of bytes that can be written
when TDFE = 1 is 64 - (transmit trigger set
number). Data written in excess of this will be
ignored.
SCTFDR indicates the number of data bytes
transmitted to SCFTDR.
